For the implementation and testing of this solution OpenShift Data Foundation was used for object storage for saving of the LoRA checkpoints during training. OpenShift Data Foundation integrates Ceph with multiple storage presentations including object storage (compatible with S3), block storage, and POSIX-compliant shared file system.
To facilitate time efficient model training/deployment and flexible model versioning, it is recommended to use fast shared storage such as a PowerScale system with the NFS CSI driver. The CSI Driver for PowerScale is part of the CSM (Container Storage Modules) open-source suite of Kubernetes storage enablers for Dell Technology (Dell) products. For more information about deployment and implementation of the CSI driver, see https://github.com/dell/csi-powerscale.
